Experimental System of Pulsed NMR Advanced Physics Experiment

This Pulsed Nuclear Magnetic Resonance (PNMR) experiment system is designed to study the principles of nuclear magnetic resonance using pulse excitation techniques. It enables students to investigate spin echo (SE), free induction decay (FID), spin-lattice relaxation (T₁), spin-spin relaxation (T₂), chemical shift, and the effects of magnetic field homogeneity and paramagnetic ions on nuclear relaxation. The system provides a comprehensive platform for advanced NMR experiments in physics laboratories. Manufactured by Atico Export India.
